Abstract

Sugar cane plantations are often located on uplands with low irrigation water sources and get water sources from rainfall. Mycorrhiza increased water absorption and effective in dry land. This research aims to determine the best watering frequency and dose of mycorrhizae for sugarcane single bud seedlings. The research was conducted at Research Garden of KUD Ngajum located in Wonosari, Malang, East Java. The research was conducted in May to August 2013. The research method was used a Completely Randomized Design (CRD) consisting of two factors. The first factor was mycorrhizal dose consisting of 4 levels: without mycorrhiza (M0), 10 g /plant (M1), 30 g/plant (M2), 50 g/plant (M3). The second factor was the frequency of watering consists of 4 levels: once a day (F1), once every two days (F2), once every three days (F3), four days (F4). Application of mycorrhizae of 10 grams, 30 grams and 50 grams had the same effect on all parameters of sugarcane seedling growth except the number of tillers, leaf area and percentage of mycorrhizal infection. Frequency of watering every 2 days gives good results on the parameters of plant dry weight. The combination of 50 grams of mycorrhizal treatment with watering frequency once every 2 days gives a good effect on leaf area while the combination of treatment of 10 grams of mycorrhizae and watering once every 4 days and my dose of 30 grams of mycorrhizae with frequency of watering once every 3 days gives a good effect on the percentage of mycorrhizal infections.

Abstract

This research aimed to determine the content of lignin, hemicellulosa and salacca midrib cellulosa and physical chemical and biological pretreatment, to determine degradation of lignin, hemicellulose and cellulose. Physical treatment used the steam explosion, chemical treatment used the NaOH and biological treatment used the Trichoderma reesei FNCC 6012. Pretreatment using the steam explosion based on temperature consisting 1200C, 1400C, and 1600C. Pretreatment using NaOH based on concentration consisting 2%, 4%, and 6%. While the pretreatment using Trichoderma reesei based on fermentation time consisting 5 days, 10 days, 15 days. The pretreatment reduced the lignin content on salacca midrib. The parameters observed lignin, hemicellulose and cellulose content. The results showed that pretreatment using Steam Explosion with a temperature of 1400C and 1600C reduced lignin levels by 16.03% and 15.90%. Pretreatment using Steam exploision temperature 1600C and Trichoderma reesei 15 days increased hemicellulose content by 35.84% and 36.21%. Pretreatment using Steam Explosion at 1600C had the best effect on cellulose at 51.09%.

Abstract

The world's increasing food needs due to the increase in population have caused humans to increasingly innovate to increase plant productivity. Smart Agriculture is the current answer that can be utilized and optimized to increase the productivity and sustainability of agricultural systems. This PkM activity was carried out online involving students in Lamandau Regency as activity participants. The aim of this PkM activity is to provide additional information and insight for students in Lamandau Regency regarding Smart Agriculture. The method used is lecture and activity stages consisting of, 1) Preparation Stage; 2) Implementation Phase and 3) Evaluation Phase. As a result of this PkM activity, understanding of Smart Agriculture among students has increased and motivated students to innovate and deepen knowledge related to Smart Agriculture.
